PERKO 0443 - Manual

Cat. No. 0443 Series
Intake Water Strainers with Clear Body
INSTALLATION AND OPERATING INSTRUCTIONS
NOTE: Prior to installation, consult your Engine Manual for recommended pipe size and strainer location. Flow charts are provided on
the back of this sheet to aid in the selection of the proper strainer size for your system. For proper protection, A.B.Y.C. Standards
E-1 (Bonding of Direct Current Systems) and E-2 (Cathodic Protection) must be adhered to.* (These Standards may be obtained
from the American Boat & Yacht Council, Inc., 613 Third Street, Suite 10, Annapolis, MD 21403).
1). The PERKO Water Strainers have been designed to be installed on the intake side of the water cooling system.
2). Mount strainer on a flat surface in a vertical position. Allow clearance above strainer to remove basket for cleaning.
3). For correct installation, note that the inlet and outlet fittings are marked on the top casting. For convenience in piping, there are
mounting lugs on both sides of the strainer.
4). Drill mounting holes, using mounting lugs on strainer as a template. Strainer should be mounted to ensure proper support from
bulkhead to eliminate any strain on the pipe.
5). PERKO strainers are designed to give 100% full flow, without restriction of pipe size (see Note No. 7). The use of reducers may
cause engine damage and therefore is not recommended. The following table shows the rated strainer open area to pipe cross-
section ratios:
Cat. No. Pipe Size Ratio
0443004PLB 1/2 55:1
0443005PLB 3/4 25:1
0443006PLB 1 20:1
0443007PLB 1-1/4 13:1
0443008PLB 1-1/2 17:1
6). After all connections are complete, start engine and check entire system for leaks.
7). IMPORTANT: Periodic inspection and removal of foreign matter is essential for safe operation. This requirement will vary, depending
on amount of use and local operating conditions. Quick cleaning of strainer is accomplished by removal of basket through access
in top in casting.
8). IMPORTANT: Periodic inspection of components is also essential for safe operation. Make sure to check castings, fasteners,
cover gaskets, plug, tie rods, etc. for damage or deterioration on a regular schedule.
9). WINTERIZING: To prevent damage by freezing, drain the strainer cylinder prior to storage in freezing temperatures.
If an antifreeze solution is used to flush the engine and remain in contact with the strainer cylinder, use only propylene glycol based
solutions. DO NOT USE ethylene glycol based solutions, as they will cause clouding of the cylinder surface.
